Japanese Patent Publication No. 4502089 disclose a kind of exhaust valve comprising pedestal can be opened or be closed compared to pedestal
The valve of conjunction and the torsional spring being pressed on the valve.Wherein, pedestal is formed by a pipe in muffler.It can be with
Understand, when exhaust system is unstable, the air-flow of high speed will lead to valve and close and open and close back and forth in opening process, and generation is made an uproar
Sound.
Therefore, it is necessary to be improved to the prior art, to solve the above technical problems.
Summary of the invention
The purpose of the present invention is to provide a kind of exhaust valves for reducing noise.
To achieve the above object, the present invention adopts the following technical scheme: a kind of exhaust valve, including valve and to drive
The spring that the valve rotates between the open position and the closed position, the exhaust valve further include hydraulic cylinder, the spring
It is at least partly socketed on the hydraulic cylinder, the hydraulic cylinder includes cylinder body and positioned at the two sides of the cylinder body
Pivot, wherein the valve can be rotated along the pivot, the hydraulic cylinder includes rotating together with the pivot
Revolving fragment and be located at the intracorporal hydraulic medium of the hydraulic cylinder, wherein the revolving fragment be equipped with perforation, when the revolving fragment
When rotation, the hydraulic medium in the side space of the revolving fragment passes through the other side that the perforation reaches the revolving fragment
Space.
Technical solution as a further improvement of that present invention, the valve are equipped with the support portion positioned at two sides, the support
Portion is equipped with the mounting hole for installing the pivot.
Technical solution as a further improvement of that present invention, the pivot is axially through the hydraulic cylinder.
Technical solution as a further improvement of that present invention, the revolving fragment include the first rotation being fixed on the pivot
Rotor and the second revolving fragment being fixed on the pivot, first revolving fragment are equipped with second revolving fragment and wear
Hole.
Technical solution as a further improvement of that present invention, the extension side of first revolving fragment and second revolving fragment
To opposite.
Technical solution as a further improvement of that present invention, the hydraulic cylinder further include the limit close to the pivot
Disk, the spring are torsional spring, and the torsional spring is limited between the position-arresting disk.
Technical solution as a further improvement of that present invention, the hydraulic medium are hydraulic oil.
Compared to the prior art, the present invention can play certain damping action by hydraulic medium, so that valve turns
Dynamic speed is slow, avoids the rapid contact with pedestal, reduces contact dynamics, reduce noise.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram of exhaust valve of the present invention.
Fig. 2 is the sectional view of hydraulic cylinder internal structure in Fig. 1.
Specific embodiment
It please join shown in Fig. 1 and Fig. 2, present invention discloses a kind of exhaust valves 100, can be applied to engine exhaust system
In, such as in noise reduction packet.The exhaust valve 100 include can relative to the valve 1 that pedestal (not shown) turns on or off, to
Drive the spring 2 rotated between the open position and the closed position of valve 1 and the hydraulic cylinder 3 matched with the valve 1.
In illustrative embodiments of the present invention, the spring 2 is torsional spring.The spring 2 is at least partly socketed in described
On hydraulic cylinder 3.
The hydraulic cylinder 3 includes cylinder body 31 and the pivot 32 positioned at the two sides of the cylinder body 31, wherein described
Valve 1 can be rotated along the pivot 32.The hydraulic cylinder 3 includes the revolving fragment rotated together with the pivot 32
33 and the hydraulic medium (such as hydraulic oil) in the hydraulic cylinder 3.It is described in illustrative embodiments of the present invention
Revolving fragment 33 includes the first revolving fragment 331 being fixed on the pivot 32 and second be fixed on the pivot 32 rotation
Piece 332, first revolving fragment 331 are equipped with perforation 333 with second revolving fragment 332.First revolving fragment 331 and institute
The extending direction for stating the second revolving fragment 332 is opposite.In addition, the hydraulic cylinder 3 further includes the position-arresting disk close to the pivot 32
34, the torsional spring is limited between the position-arresting disk 34.
The valve 1 is equipped with the support portion 11 positioned at two sides, and the support portion 11 is equipped with the installation for installing the pivot 32
Hole 12, so that the valve 1 can be rotated along the pivot 32.The pivot 32 is axially through described hydraulic
Cylinder body 3.
When high-speed flow is blown along arrow, 1 stress of valve rotates backward around pivot 32, at this time 2 stress of spring to
After rotate.At the same time, revolving fragment 33 with holes in hydraulic cylinder 3 passes through the perforation 33 of revolving fragment 33 also with pivoting
It is flowed with the gap of surrounding.That is, the hydraulic medium being located in the side space of the revolving fragment 33 passes through the perforation 33
Reach the other side space of the revolving fragment 33.Hydraulic medium (such as hydraulic oil) has certain stickiness, can play certain
Damping action avoids the rapid contact with pedestal, reduces contact dynamics, reduce so that the speed of the rotation of valve 1 is slow
Noise.
When air velocity reduces, return spring power is greater than the power that air-flow generates, and valve 1 is pressed downward, valve 1 is around pivot
Rotation before axial.Revolving fragment 33 with holes passes through the perforation 33 and surrounding of revolving fragment 33 also with pivoting in hydraulic cylinder 3
Gap flowed.Due to the damping action of hydraulic medium, valve 1 is rotated slowly, smaller with base into contact power.It completely attaches to
Afterwards, hydraulic medium has continued damping action, and valve 1 is not in opening and close back and forth, reduces noise.
In addition, above embodiments are merely to illustrate the present invention and not limit the technical scheme described by the invention, to this
The understanding of specification should be based on person of ordinary skill in the field, although this specification is referring to the above embodiments pair
Present invention has been detailed description, still, those skilled in the art should understand that, the technology of technical field
Personnel still can modify or equivalently replace the present invention, and all do not depart from the technology of the spirit and scope of the present invention
Scheme and its improvement should all be covered in scope of the presently claimed invention.
